SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 589,854, datedSeptember 14, 1897. Application filed June 12, 1896. fierial No.595,263. (No model.)

' a citizen of the United States, residing at Kan sas Gity,in the countyof Wyan dotte and State of Kansas, have invented certain new and usefulImprovements in Door-Hinges; and I do hereby declare the following to bea full, clear, and exactdescription of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in door-hinges, the object of thesame being to provide a simple and cheaply-constructed two-way hingewhereby a door may be opened. in either direction and in which a singlespring for returning the door to normal po-.

sition is employed.

The invention consists of a block having an elongated slot thereinhinged to the doorframe and extending longitudinally thereof, a spiralspring moving Within said slot and secured at its lower end, a doorhinged to said block atthe corner opposite to the hinged joint betweensaid block and said door-frame, pulleys mounted transversely in saidblock in the upper end thereof, and a pair of chains or cords secured tothe upper end of said spring, passing around said pulleys, and attached,respectively, to the door-frame and the door.

The invention is clearly illustrated in the accompanying drawings, inWl1lCl1 Figure 1 represents a side elevation of my door-hinge in itsnormal or closed position. Fig. 2 is an edge view of the same. Fig. 3 isa top plan view. Fig. lis a horizontal section. Fig. 5 is a detailperspective view of the block in which the closing-spring is mounted.

Like reference-numerals indicate like parts in the different views.

Hinged to the side of the door-frame 1 is a block 2, having an elongatedslot 3 therein formed with side arms 4.- 4 at its upper end and having apair of transverse rollers 5 5 pivotally mounted in said arms. FittingWithin the slot 3 in the block 2 and secured at its lower end to saidblock is a spiral spring 6, and hinged to the edge of the block 2,opposite the hinged joint between said block and the door-frame 1, is adoor 7. Secured to the upper end of the spring 6 and passing around thepulleys 5 5 are chains or cords 8 9, which. are connected, respectively,to the upper edges of the door-frame l and the door '7.

As thus constructed, it will be seen that the door 7 is capable of beingopened in either direction and that it will be returned to its normalclosed position by the action of the spring 6 and the cords 8 9.

The device is extremely simple in construction, can be cheaply made, andcan be applied to any door now in use.

Having 110W described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a door-frame of a block hinged at one corner tosaid frame, a spring mounted in said block, a door hinged to theopposite corner of said block and cords connected to one end of saidspring and at tached to said door and frame respectively, substantiallyas and for the purpose described. Y

2. The combination with a door-frame of a block having an elongatedslottherein, hinged at one corner to said frame, a coiled spring movingWithin said slot and secured at one end to said block, a pair of rollerspivotally mounted in the upper end of said block, a door hinged to theopposite corner of said block and chains or cords connected to the freeend of said spring, passing around said rollers and attachedrespectively to said door and frame, substantially as and for thepurpose described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
